Filed: 1971-08-27
Abstract: 1353235 Tyre building drums EAGLEPICHER INDUSTRIES Inc 27 Aug 1971 [3 June 1971] 40370/71 Heading B7C A collapsible tyre building drum comprises a plurality of arcuate segments 12, 14 radially slidably mounted on guide posts 21 fixed to a hub 16 which, in use, is mounted on a power shaft 15 and is connected through a coupling 19 and a sleeve 20 to a brake, a plurality of cam followers 31 mounted on flanges 25 on the segments 12, 14, and a pair of plates 26 having cam slots 29, 30 engaged with the followers 31, the plates being secured to a sleeve 28 which is mounted on the hub 16 and is fixed, in use, to the shaft 15 by a bolt 35 passing into the shaft through an aperture in the sleeve 28 and a slot (36) [Fig. 4, not shown] in the hub.  In operation, expansion of the drum from the collapsed condition shown in Fig. 3, in which the shaft 15 is stationary, is achieved by starting rotation of the shaft 15 whilst holding the hub 16 stationary by means of the brake, which allows the shaft, and thus the sleeve 28, to rotate relative to the hub because of the slot (36) and thus causes the slots 29, 30 to be moved until the followers 31 are located at the outer ends of the slots, thereby displacing the segments 12, 14 to their radially outermost positions shown in Fig. 1. Release of the hub brake and continued rotation of the shaft 15 then results in rotation of the hub, and thus of the expanded drum, with the shaft 15. Collapse of the drum is effected by stopping the shaft 15 which results, because of the slot (36), in the hub rotating relative to the shaft and sleeve 28, thereby moving the followers 31 to the inner end of the slots 29, 30 and causing the segments 12, 14 to be displaced to their radially inner positions as shown in Fig. 3. The hub brake is applied during the collapsing operation to prevent the followers engaging the inner end of the slots 29, 30 with too great a force. As illustrated in Fig. 3, the segments 14 are of smaller arcuate extent than those 12, and the cam slots 30 are of different pitch to those 29, such that the segments 14 are displaced radially inwardly of those 12 on collapse of the drum, but interfit with those 12 to form a continuous surface in the expanded condition of the drum.

Abstract: 1435085 Shrink and crease proofing keratinous material CIBA-GEIGY AG and IWS NOMINEE CO Ltd 15 Aug 1973 [1 Sept 1972] 40646/72 Heading D1P Keratinous material is proofed against felting shrinkage, relaxation shrinkage and creasing and existing or future pressing is rendered more durable by treating the material with a polyene having at least two olefinic double bonds each beta to an oxygen, nitrogen or sulphur atom and curing the polyene on the material by reaction with a polymercaptan having at least two mercaptan groups, the combined weight of polyene and polymercaptan incorporated in the product being 0.5 to 15% by weight of the keratinous material treated. The sum of the number of mercapto groups and the number of said olefinic double bonds is more than 4, e.g. 5 to 8. The polymercaptan comprises either the residue of a polyhydric alcohol after removal of its alcoholic hydroxyl groups or the polyacyl residue of a polycarboxylic acid, with bound to the residue through ether or ester oxygen atoms at least two chains each containing either the residue of a dihydric alcohol after removal of its hydroxyl groups or the diacyl residue of a dicarboxylic acid, with bound through ether or ester oxygen atoms to said residues of a dihydric alcohol or a dicarboxylic acid either an acyl residue of an aliphatic mercaptancarboxylic acid or a residue of an aliphatic mercaptanalcohol after removal of a hydroxyl group. The keratinous material may be sheeps wool, alpaca, cashmere, mohair, vicuna, guanaco, camel hair, llama hair or blends thereof. It may be blended with polyamide, polyester, polaycrylonitrile or regenerated cellulose. The material may be in the form of fibres, filaments, fleeces, tops, card sliver, noils, yarns, threads and woven, knitted, non-woven and pile fabrics. The polyene and polymercaptan may have applied in either order or together as an aqueous solution or dispersion or non-aqueous solution. Preferably 0.8 to 1.2 mercaptan groups are present per olefinic double bond. The reactants may be applied to the material by. padding or immersing the material in a bath, by spraying or by exhaustion from aqueous solution or emulsion. Curing i.e. reaction of the polymercaptan with the polyene may be facilitated by catalyst by acids, amines or peroxides and/or by heating to 35 to 180C. A fabric may be flat set before or after treatment with the polyene and the polymercaptan using steam a swelling agent (e.g. urea) and diethanolamine carbonate or a swelling agent and a reducing agent. In example 1 run 3 the the polyene i.e. (XLI) where E stands for COCH=CHCOOH and the polymercaptan (the tris(thioglycollate) of a glycerol-propylene oxide polyol) and diethylene tetramine as catalyst were dissolved in perchloroethylene and padded onto a wool flannel to 300% uptake and dried in a fanned oven at 65C for 15 minutes.

Title: Improvements in reciprocating pumps and in particular fuel injection pumps for internal-combustion engines
IPC: F02M59/36
Filed: 1958-12-18
Abstract: 897,671. Fuel injection pumps. BESSIERE, P. E. Dec. 18, 1958 [Dec. 24, 1957; June 2, 1958], No. 40930/58. Class 102(1). [Also in Group XXIX] A fuel injection pump comprises a main piston 1 reciprocating in a cylinder 3 having an inlet 4, an outlet 5 and a by-pass 7 controlled by a valve 8. The valve 8 is actuated by an auxiliary pump piston 11, reciprocating with the main piston 1, which delivers fuel, after closing a valve 25 through a conduits 14, 14a, 17, throttle 21 and an outlet 17a. The inlet 13 of the auxiliary pump is so arranged relative to the inlet 4 of the main pump that the auxiliary pump delivers liquid with a constant phase advance relative to the delivery of the main pump. At low speeds the pressure acting on the end of the valve 8 is not sufficient to move this valve against a spring loading 9 but above a predetermined speed, the pressure covers the valve and in so doing reduces the throttle 21 causing a greater pressure increase until the throttle 21 is closed. The valve 8 then moves immediately to open the by-pass 7 and a second groove 23 reopens conduit 17 to 17a to maintain the by-pass valve open. The phase advance provides for the by-pass to be opened before the main piston closes the inlet 4 above a predetermined speed. An abutment 20 is adjustable to vary the initial setting of the throttle 21. In a modification, auxiliary pump delivery acts on a ball in the manner of a flow meter to close an outlet from the chamber below the valve 8.

To stop interference from stray light &c., the mirror 11, 11a is in the form of a two strips bounded on either of their long sides by opaque non-reflecting portions 13, 14 and leaving a slit light passage 15. The stray light then falls on the opaque portions. An alternative way of achieving this configuration is shown in Fig. 5 wherein the reflective surface is at 16 and the opaque portions and slit are together defined by surfaces 18, 19 rising perpendicularly from the mirror. To compensate for the increase in brightness of the image with decreasing range, surfaces 18, 19 may be automatically moved from the mirror, (Fig. 6, not shown). Similar compensation may be produced by making the width of the mirrors decrease away from the slit and that of the slit, now in two halves to decrease towards the axis 7 of the system (Fig. 7, not shown).
